IMPROVEMENT IN CHECK-ROW ATTACHMENTS TO SEED-PLANTERS.

Specification forming part of Letters Patent No. 19 [,528, dated J une5, 1877; application filed April 27, 1877.

10 all whom it may concern:

Be it known that I, GEORGE D, HAWORTH, of Decatur, county of Macon,State of Illinois, have invented certain new and useful Improvements inCheck-Row Attachments to Seed- Planters, of which the following is afull, clear, and exact description, reference being bad to theaccompanying drawing, making part of the specification, in which- Figure1 is a perspective view of my improved check-rower attachment toseed-planters. Fig. 2 represents a vertical section through the sameenlarged. Fig. 3 is a front elevation, and Fig. 4 a plan view, of thesame.

Similar letters of reference denote corresponding parts in all thefigures.

My invention relatesto the means for operating the seed devices; andconsists in a novel construction of the vibrating arm or lever operatedupon by the check-row cord or wire, whereby it is adapted to be vibratedin opposite directions alternately by said cord or wire while thelatteris moving continuously across or over it in one direction; theobject being to avoid the duplication of levers heretofore employed, andthus to simplify the construction of the check-rower attachment, and toobviate, as far as possible, all liability of its getting out of order.

In the accompanying drawings, A represents the frame-bar of thecheck-rower attachment, and upon which the guides or pulleys for guidingthe check-row cord or wire, and the means operated upon by said cord orwire for actuating the seeding devices, are mounted, said bar, togetherwith the lever a, through which motion is imparted to the seedingdevices, being made in any usual or preferred form. At or near midway ofthe length of bar A, and directly over the pivot of lever a, is a forkedlever, B, pivoted midway of its length upon the bar A, or upon asuitable standard or support, A, thereon, as shown. This lever has .itsends recurved or bent back upon itself; or, in other words, the centralportion is cut away in thickness for a portion of its length, and thethicker ends, where not cut away, are slit outward toward the ends, asshown at c in Fig. 4. The recurved ends B B are made in form resemblingan arrowhead, or the arms of an anchor, with the points set opposingeach other, and the arms b b inclining outward, and forming an acuteangle each with the outer ends of the lever, as shown. The body of thelever is provided with similar arms b, arranged in the same planes,transversely to the lever, with the arms b, (see Figs. 1 and 2,) andjust outside of the junction of these arms b and b with their respectiveshanks, the slots between the lever B proper and its recurved ends B Bare enlarged, and made cylindrical in form at c, to permit the passageof the knots or projections on the cord or wire after they escape fromthe arms b b, as hereinafter explained. The slotted and forked arm orlever B, with its recurved ends B B and arms b b, as described, may, ifdesired, be cast or otherwise made in a single piece, and forms thesingle device or lever acted upon by the check-row cord or wire foroperating the seeding devices.

This arm, as above stated, is pivoted mid way of its length to theframebar A, and immediately under its pivot is provided with a pin,which engages with the forked lever a, connecting it with the seedingdevices.

The operation is as follows: Supposing the lever B to be in theposition-indicated in Figs. 1 and 2, with the cord D moving relativelyto the same in the direction indicated by the arrow, Fig. 2. In thisposition the cord lies in the slot 0 between two oblique parallel arms,b b, and as it moves along the knot enters the angle or fork 00 betweensaid arms and their shanks, and, engaging therewith, draws the lever Bover into the reversed position shown in Fig. 3, when the reverseinclination of the shank allows the knot to slide slightly outwardtoward the end of the lever, and thus to enter and pass through theenlargement c of the slot, and to escape from the lever, leaving thelatter in position for the succeeding knot or protuberance on the cordor wire to enter the fork to on the opposite end of the lever, and,acting thereon, to reverse the movement of the lever, and bring it toits first-named position, in readiness to be again acted upon by thecord or wire.

By this arrangement it will be seen that the single lever B is adaptedto be operated in both directions by the cord moving in one directiononly, and the system of levers and links heretofore required toaccomplish this result is dispensed with. The forks x x on the oppositeside of the lever are acted upon by the cord when the machine or thecord or wire relatively to the lever is moving in the reverse direction.Stops at d d serve to limit the throw of the lever B, and to hold it inproper position to be acted upon by the cord or wire alternately uponits opposite ends, as explained.

The form of the arm or lever B may be varied, and any suitableconnecting devices may be employed, without departing from my invention,so long as asingle lever, acted upon by the check-row cord or wire, isadapted to be vibrated alternately in opposite directions by the directaction thereon oi the cord or wire, moving continuously in one directiononly.

Having now described my invention, what I claim as new, and desire tosecure by Let ers Patent, is-

1. In a check-row planter, an arm or lever made in a single piece, andadapted to be operated alternately in opposite directions by the directaction of the check-row cord or wire thereon, as explained.

2. The arm or lever B, provided with the recnrved and slotted and forkedends, substantially as and for the purpose set forth.

3. The arm or lever B, pivoted midway of its length, and provided withthe recurved or slotted ends, and with the diverging arms or forks b 11,substantially as described.

4. The lever a, through which motion is communicated to the seedingdevices, connected directly with, and receiving a positive movement inboth directions from, the single vibrating check-row-cord arm or leverB, substantially as described.
